Netrunner (17.10), Firefox 52 only, all hardware detected and functionnal, but unable to install Digikam
Netrunner Rolling, all hardware were detected but unable to print any document. The usual printer HP-1200 is detected, the driver installed, but at all attempts : printer not responding whatever the driver. That reminds me the behaviour I observed with a rpm base distribution like Mageia. That is why I moved some years ago to Netrunner and then Maui.
My main applications were OK.

Manjaro, Antergos are also unable to setup my printer with the same message : printer not responding;
Thus this not link to Netrunner Rolling, but to some configuration file with bad permissions ? but which one ?
